Jan 07, 2021 ยท Chevrolet Caprice (1991 โ€“ 1993) โ€“ fuse box diagram. Year of production: 1991, 1992, 1993. Fuse box diagram ... Power Vent Motor (โ€™91) 22 .... I just put a new distributor in my 91 Chevy caprice classic 305 V8 TBI and I forgot to mark on the cap where exactly the cyl #1 plug wire position. I have the right firing order and cyl placement and the new dist. went in facing the same way the old one came out,(with exception of the spline gear and rotor) So I need to know where pos # XXXXX is on the cap so I can set the gear and rotor to #1.
